Product Description:

The MAC090B-0-ND-4-C/110-A-1/WI520L is a brushless AC servo motor manufactured by Bosch Rexroth Indramat and supplied within the MAC AC Servo Motors series. Designed as a motor for analog drives, it converts controlled electrical input into rotational motion with tightly regulated speed and torque. In automated assembly lines, packaging equipment, and material-handling axes, this unit pairs with legacy analog amplifiers to execute repeatable positioning tasks. Its electromechanical design supports medium frame applications where a compact footprint and precise response are required.

The motor seats against machinery via a 110 mm centering diameter, allowing concentric alignment between the shaft and the driven element to minimize radial load. Thermal energy leaves the housing through natural convection, so no active blower or coolant circuit is needed under rated duty. A standard blocking brake is installed; when supply power is removed, the brake clamps the shaft to hold loads or preserve position. Power enters through a connector on side A, positioning the cable exit toward the drive cabinet for routing. For speed and position evaluation, the unit can be configured with tachofeedback and an incremental or absolute encoder. This arrangement sends an analog velocity signal to the amplifier while also supplying position data to the controller.

The signal chain is completed by an incremental encoder with standard mounting that delivers uniform 1 Vpp or TTL increments, supporting stable feedback transfer to compatible control hardware. Motion smoothness is reinforced by the standard tacho quality, which helps keep velocity ripple low during contouring and steady-speed operation. These feedback channels allow the drive and controller to process motion data at the same time instead of relying on a single signal source. This setup is useful on axes that need stable speed control during motion and dependable position tracking during indexing.
